CONTR'IVANCE FOR CLEANING COOKING UTENSILS AND OTHER .AIRflIllC-EIS.l

To allwkom 1f/ may concern.'

Be it known that I, EDWIN M. GOLD- sMrrH, a citizen of the UnitedStates, residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented a new and useful Improvement in Contrivancesfor Cleaning Cooking Utensils and other Articles, of which the followingis a full, clear, and exact description, reference lbeing had to theaccompanying drawings, which form a part of this specification.

y The object of my invention is to provide a cleaning contrivanceadapted Vfor the removal from cooking utensils of dirt, grease andadhesive substances which resist relnoval by means of wash rags and soapand hot water. For this purpose the use of abrasive material, such asmeta-l chains, or woven or knitted fabrics interwound with non-corrosivemetal, such as copper thread, is known; but such devices, whileeffective so far as concerns their abrading fu-nctions, possess littleor no absorbent properties and are therefore ineffective except whensupplemented by independent treatment with wash rags.

The more specific object of my invention is to provide a cleaningcontrivance which, when rubbed back and forthV over the surface to becleaned, will, by frictional action, remove the material adhering tosuch surface and will also be effective to yabsorb the water which hasdissolved, or which carries in suspension, the removed material, andwh-ich will be capable of removing both the material which resistsremoval by means of a non-abrasive rag and the material for the removalof which a non-abrasive rag or the like is best adapted.

The invention is capable of many different specific embodiments. Asexamples, I have shown in the drawings two preferred constructions whichhave been found effective in practical use.

Figures l and 2 are face views of such embodiments of my invention. l

The base of the fabric shown in Fig. 1 is a woven or knitted fabric aformed of relatively coarse threads spaced apart to form interstices ofsubstantial size. The`r degree of closeness of the -weave is not anessential feature of the invention, but the use of a coarse open fabricis preferred. At intervals throughout a part of the surface areSpecification ofL Letters Patent.

formed orifices b of a diameter substantially greater than the spacebetween adjacent parallel threads, said orifices being reinforced aroundtheir edges to prevent fraying. Whether the fabric be woven or knitted,the designing of the fabric will be much facilitated by providing for aplurality of rows of orifices the orifices of each row being spacedapart at regular intervals, as shown. Such an arrangement of orifices,while non-essential, also facilitates the attachment of the abrasivematerial to the fabric, as is hereinafter explained. 7

I prefer to employ, as the abrasive material, a spira-l metal coil orcoils c, as shown in Fig. l, or an ordinary link chain d, as shown inFig. 2, although the invention is not limited specifically to coils orchains. In Fig. l, two continuous'or endless spiral coils are shown,each coil being interlaced with the fab-ric by extending it throughadjacent orifices b and alternately from one face to the other, so that,in the finished article, an approximately equal length of coil overliesboth faces. Y

In Fig. 2, three chains ai are interlaced with the fabric and extendalong three para lel rows of ori'fices b, each chain extendingalternately from one face to the other, the corresponding ends of thetwo outer chains being united to each other and to the corresponding endof the central chain so that` they form, in effect, one integralstructure.

It is preferred tapply the abrasive agent to only a part of the fabric,the same being arranged preferably wholly or partly across the fabricmidway between opposite edges, so that at least one third of the area ofthe entire fabric along each of said edges presents a whollynon-abrasive surface'. These portions of the fabric may be folded overthe portion that is reinforced with abrasive materialso as to cover thelatter and render the cleaning contrivance wholly non-abrasive. In thepreferred form shown, even that part of the fabric with which thechains, coils or the like interlace has the larger part of its areauncovered, the chains or coils extending only along lines connectingadjacent orifices I). Hence, even that part of the fabric that isreinforced with abrasive material possesses considerable absorptiveproperties.

Nor do I mean, bythe use of the term textile material to exclude theemployment of any other relatively thin and superficially extended basehaving absorbent and relatively non-abrasive properties.

Having now fully described my invention, what I claim and desire toprotect by Letters Patent is:

1. A cleanin contrivance comprising an unsupported p iable piece offabric a large part of the surface of which is uncovered, the uncoveredpart acting wholly as an absorbent, and abrasive material bothpositively secured to the fabric and so extending superficially over theremaining part of said surface as to leave a substantial portion of theabrasive section of the fabric uncovered, thereby providing a exiblecleaning contrivance one -section Which is Wholly absorbent and anothersection which is both absorbent and abrasive.

2. A cleaning contrivance comprising a textile fabric provided withorifices other than the normal interstices between the threads of thefabric, and means, embodying abrasive material, engaging said holes andthereby held upon the surface of the fabric so as. to a'ord means forremoval by frictional'abrasion of substances resistant to removal byrelatively non-abrasive absorbent material.

3. A cleaning contrivance comprising a 40 textile fabric providedA withorifices and means interlacing with the fabric by extending through saidorifices from one face of the fabric to the other, said means embodyingabrasive material adapted to overlie A5 the face of the fabric.

4. A cleanin contrivance comprising a base of textile abric providedWith orifices and a string of abraswe material interlacing with theorifices and extending therethrough from one face of the fabric to theother and extending also over both'faces of the fabrics from one orificeto another.

5. A cleanin contrivance comprising a base of textile fa sive metallicmaterial carried thereby and distributed over a part only of itssurface, a substantial part of the surface upon which the abrasivematerial is distributed being uncovered by the abrasive material andpresenting a non-abrasive absorbent surface.

6. A cleaning contrivance comprising a base of textile fabric andstrings of abrasive material attached to both faces of the fabric so asto leave uncovered substantial superficial areas of absorbent andrelatively nonabrasive material.

In testimony of which invention, I have hereunto set my hand, atPhiladelphia, Pa.,

on this 12th day of January, 1918.
